You dont have to install sendmail, so do not change your mail setup! Postfix is fine as it has a sendmail warpper. You can not send emails from a dsl line directly as all major email providers will block your emails as spam. You have to configure your system to relay the email trogh a trusted external mailserver. http://www.howtoforge.com/postfix_relaying_through_another_mailserver
